SPECIFICATION formingpart of Letters Patent No. 730,204, dated June 2, 1903.

Application filed A ln 25, 1902.

To a whom it may concern.-

Be it known that I, THOMAS EDwARDaa citizen of the United Statesof America, residing at Holyoke, in the county of .Hampden and State of Massach usetts,have invented new and-useful Improvements in Means for Automatically Delivering Ashes from an Ash-Sifting Device to a Flue, of which-the following is a specification. V

This invention relates to devices for automatically delivering ashes from an ash-Sifter to a fine, which are adapted to be attached to an ash-receiving flue in a room or building, the object being to provide devices of this class of improved and simplified construction; and the invention consists in the peculiar construction and arrangement of the several parts of the device, all as hereinafter described, and more particularly pointed out in the claim. i

In the drawings forming part of this specification, Figure 1 is a vertical sectional View of the Sifter on line 1 1, Fig. 2, and shows a vertical section of said ash-receiving flue behind the sifter, to which thelatter is attached for support and for operation. Fig. 2 is a vertical sectional view of the Sifter on line 2 2, Fig. 1.

Referring to the drawings,A indicates a vertical metallic ash receiving and conducting flue adapted to be located at one side of a chimney or Wall, as indicated in the drawings, to the side of which may be suitably connected The front side of said conducting-flue, against which the ash-sifting device is applied, has an opening B extending, preferably, upwardly from a pointa little below the top of the floor 8 of the room in which the sifting device is located, as shown, and the rear side of the Sifter-case has a similar opening therein, which in practice is maintained opposite that in said conducting-flue, whereby waste matter may be discharged from said case into said flue. The portion of said ash receiving and conducting flue A against which the Sifter-case is applied has inturned border-flanges 9, which engage the vertical borders of the back 7 of the sifter-case, as shown in Fig. 2, thereby firmly holding the same in operative relation to the flue. It will thus be understood that the sifter is slidingly engaged with the fine, where- Serial No. 104,650. (No model.)

by it may be conveniently connected with or disconnected from the same. A single metallic plate forms a back section 2 and the top a of said case, which is folded at the upper end to form the vertical lip 3, and from.

the base of saidlip the plate extends forwardly and forms said top. 0n the forward borderof said topa is secureda suitable hinge or hinges 4, by which the'cover 5 is hung to swing in opening and closing, the position of which cover when opened-is indicated in dotted lines inFig. 1. The' front wall 6 of said sifter-caseextendsin an upwardly-inclined directionfrom the bottom of the case to a point somewhat below the said top, as shown in Fig. 1, to facilitate the manipulation of a Sifter-pan, (below described) the sides 10 and said front wall constituting a hopper-like form of case, in which the sifting of said matters is effected, as'belowdescribed, and which catches the ashesresult ing therefrom. The said communicating opening between the interior of the Siftercase and said ash receiving and conducting flue is kept normally closed by the automate ically-operating gate 0, Whichishung 'onthe lower border of theback 2 of the Sifter-case, as shown in Fig. I. Said gate from its lower edge upwardly for most of its length is of spoon-like shape in section, thereby forming somewhat of a pocket for holding ashes and bringing the edge of the lower end of the gate to a closed position against the inner side of said front 6. A weight D is attached to said gate and serves to swing and hold said lower border thereof in said closed position and also to act with sufficient gravity-power to retain the gate closed against a considerable accumulation of ashes thereabove. edge ofthe gate Qis by said weight Dso held against the wall 6 as to prevent dust from blowing from-the fine A into the Sifter-case and thence into the room where said case is located.

On the inner opposite walls of the sides 10 of the Sifter-hopper are secured two strips 12 of bracket-like form in transverse section,-

which form supports for an ash-sifting pan 13, on which is a handle 14, extending outwardly through an opening in the front wall 6 of the hopper, just under said cover 5. Said pan is constructed principally of wire- Said lower I cloth and is adapted to have a reciprocating movement on its said supporting-strips imparted thereto by a person grasping said handle, whereby the ashes and other fine matter deposited in said pan are sifted from the cinders therein and fall downward to be caught between said gate and said wall 6, and when a certain quantity becomes there accu mulated said gate swings away from said wall and discharges the matter held thereon into the chute, through which it drops below. It will be noted, as shown in Fig. 1, that the lower extremity of said hopper extends more or less through the floor 8 of the room, and to form a firm support for the hopper independent of the flue A a metallic elbow-brace E is applied to the lower part of the hopper, and bearing on said floor it firmly supports the hopper against any downward movement under any load to which it may be subjected.

The operation of the devices in sifting ashes, &c., is quite obvious and is usually effected in the following order: Ashes and cinders are placed in said Sifter-pan 13, the cover 5 of the hopper is shut, and the contents of said pan are agitated by shaking the same, and the ashes and fine matter fall into the hopper,. mainly against said gate, and the cleaned cinders, 650., may then be removed from said pan.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

A device for sifting ashes periodically and automatically permitting the waste material resulting from the act of sifting to be discharged therefrom, comprising the case having a back section 2, the top a, and the inclined front 6, said back section terminating about midway of the opposite ends of the case, thereby leaving an opening for the escape of waste ash material therefrom, the door 5 hinged on said top, the case sides 10, 10, the ash-pan-supporting strips 12, the gate 0 having a spoon-like form hung to swing freely on the lower edge of said back, actuated by sifted material lying thereagainst, and a weight D fixed on said gate and returning the free end thereof against said front, combined and operating substantially as set forth.
